MEANS FOR FLUSHING RECEPTACLES.

Specification of Letters Patent.

Patented April 14, 1908.

Application filed April 12, 1906. Serial No. 311,343.

To-all whom it may concern:

Be it known that I, JOHN W. GRANTLAND, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented new and useful Improvements in Means forFlushing Receptacles, of which the following is a specification.

My invention relates to means for flushing rece tacles, chiefly intendedfor flushing the bow s of water-closets and the like and has for itsobject to provide a new arrangement, combination and mode of operation,of parts for starting, with certainty and in a simple manner, thesiphonic discharge of fluid from a tank or reservoir.

The invention consists in means possessing the features hereinafterdescribed.

Thatl which is regarded as new will be set forth in the clauses of claimappended to the description.

In the accompanying drawings in which is shown that which I regard asthe best known embodiment of my invention, and in which one manner ofuse is illustrated.

Figure 1 is a side elevation, parts appearing in section, and theapparatus being in initial position. Fig. 2 is a similar view of thoseparts of the mechanism adjacent the tank or reservoir, in set positionready for automatic action. Figs. 3, 4 and 5 are iront elevations of thesiphon and adjacent parts, showing different positions thereof duringdifferent stages of operation.

In said drawings 1 designates the tank or reservoir to contain theflushing fluid, 2 a bowl to be hushed, and 3 a conduit for conductingthe fluid from the tank to the fluid.

Within the tank is a siphon 4 one leg of which is open to the tank andthe other communicates with conduit 3, and has valved communication withthe tank. The siphonic action is started by opening the v'alvedcommunication between the tank and the conduit, and in the preferredtype of mechanism the valve is opened by moving the siphon itself, whichconstitutes a connection between the valve and the valve-openingmechanism. In some aspects of my invention it is not limited to amovable siphon, as the combination of elements making up thevalve-opening mechanism may be otherwise connected to the valve.Therefore, except in respect of those claims where a movable siphon isex- `derstood as not limited thereto.

pressly mentioned the invention is to vbe un- Proceeding with thedescription of the preferred example of the invention, the valve shown,is connected to or formed with the longer leg of the siphon and is ofcage type, that is to say, it has an open guide-extension 5 and agasketed passage-closing head 6. The guide exten- Sion 5 works in theconduit 3, its different positions being shown in Figs. 3, 4 and 5.

Connected to the valve, the siphon constituting the connecting link, isan arm? the stem 8 of which passes through and is guided in a bracket 9supported by the tank. The arm 7 is provided with a lever-race 7a. Agravity catch 1() is pivotally connected to the arm and normally standswith its nose lOfl across the race 7a in the path of the leverhereinafter referred to. The catch is provided with a trip 11 with whichcoperates a stationary element, in the present example, consisting ofthe bracket 9. The arm 7 is provided with a plurality of holes 12 toreceive the pivot of the catch to provide for proper adjustment of thelatter.

13 designates a lever suitably fulcrumed, for instance, as shown, upon apart 14 of the bracket 9, and having one end 13b disposed in therace-way 7'a in position to co-act with the catch 10 to lift the siphonand start the siphonic flushing operation. The other end of the lever 13is adjustably connected to a operating rod 15, so that it may beadjusted with relation to said rod in consonance with the adjustedposition of the catch 10. The

preferred means of connection, which is shown in the drawings,consistsof a box 16 fitted upon the screw threaded end 15a of the rod15, so that itv may be screwed up and down thereon and held by a nut 17.The corresponding end 13a of lever 13, straddles the rod and with thebox, forms a socket joint. v

The operating rod 15 is arranged to be moved in one direction to set theseveral ele ments for operation, and in an opposite direction to cause acycle of operation thereof. These movements of the rod may beaccomplished automatically, and I regard the arrangement by which it maybe so actuated as ately starts the siphonic action.

same is not essential to those clauses of appended claim which do notmake reference thereto.

Referring now to an automatic operation the rod 15 is made topreponderate in weight as compared with the operative weight of thesiphon and its closely associated parts added to that of the rodactuating means, whereby the several parts are normally in positionshown in Figs. 1 and 3. The rod actuating means consists of a lever, onearm 18 of whichis designed to conform to the place to be flushed and isdesigned to be actuated by pressure, and the other arm 19 of which isconnected to the rod 15.

In practice, the operation of the device illustrated, and for thispurpose the automatic operating arrangement will be referred to, theinitial position of the several parts shown in Figs. 1 and 3, exists byreason of the preponderance in weight of the rod l5, referred to, or byreason of the mechanical equivalent of that preponderance. When pressureis applied to the lever arm 18 the rod 15 is moved in a direction torock the lever 13 to the position shown in Figs. 2 and 4 of the drawing,the end 13b of the lever which is disposed in the lever race, pushingthe catch 10 out of the way in passing from the position shown in Fig.3, to that shown in Fig. 4. After the end of the lever has so passed,the catch, by gravity is interposed across the race 7 a and into thepath of movement of the end 13b of the lever, as in Fig. 4, in whichosition the parts are set for operation. FVhen pressure is removed fromthe lever arm 18 the rod 15, by reason of its aforesaid preponderance inWeight, rocks the lever and in this movement end 13b of the leverengages the nose 10a of the catch 10, and lifts the arm 7 and the siphon4 and opens communication between the tank 1 and the conduit 3 leadingto the place to be flushed. rIhe passage of water from the tank intoconduit 3 immedi- During the active lifting stroke of the lever 13, thetrip 13, coperating with the stationary element, such as the bracket 9,withdraws the nose of the catch from in front of the lever, as shown inFig. 5, whereupon the siphon falls, closing the communication throughthe valve between the tank and the conduit. The siphonic action,however, having been started, continues until the fluid in the tank isexhausted. When the siphon drops as described, the end 13b of lever 13will be in position shown in Fig. 3, that it to say, in initial positionin readiness for a further cycle of operation.

By my invention I provide a iushin means embodying novel elements, andnove combinations and arrangements of elements and mode of operation,whereby siphonic flushing is accomplished in a simple, eiificient andcertain manner.

I-Iaving thus described my invention, what I claim is 1. In a ilushingapparatus, the combination of a movable siphon having an arm risingtherefrom, a gravity catch pivotally connected to said arm and providedwith a nose normallyprojecting beyond an edge of the arm and with atrip, an operating lever having a portion extending across said armnormally below'said nose, and a Jfixed element cooperating with the tripto release the nose from engagement with the lever when the siphon islifted.
